Nov 21, 2008 The problem with coal is that it is a solid, and it is much more difficult to remove impurities than for fluid fuels, like natural gas or oil. Natural gas and oil are currently processed to remove sulfur compounds. Because they are fluid, they can be easily mixed with other chemicals that remove the sulfur.

Carbon filtering Wikipedia

Carbon filtering is commonly used for water purification, air filtering and industrial gas processing, for example the removal of siloxanes and hydrogen sulfide from biogas. It is also used in a number of other applications, including respirator masks, the purification of sugarcane,some methods of coffee decaffeination,and in the recovery

The function of a coal breaker is to break coal into pieces and sort them into categories of nearly uniform size. The second function is to remove as many impurities as economically desirable and feasible. Then the coal was graded based on the percent of impurities remaining. The breaker boys would work a labor intensive 10 hours a day, 6 days

Bituminous Coal Characteristics and Applications

Jan 29, 2020 Bituminous coal contains the mineral pyrite, which serves as a host for impurities such as arsenic and mercury. Burning the coal releases trace mineral impurities into the air as pollution. During combustion, approximately 95 percent of bituminous coal's sulfur content gets oxidized and released as gaseous sulfur oxides.
